1. A system for collecting bodily fluid from a subject, the system comprising:
a housing including a base having (a) a lower surface configured to be positioned against skin of the subject and (b) an aperture extending therethrough;
an outflow channel fluidly connected to the aperture and configured to receive a flow of the bodily fluid from the aperture; and
an elongate collection cartridge extending along an axis, wherein the collection cartridge is configured to be releasably coupled to the housing via a coupling portion, wherein a portion of the outflow channel extends through the coupling portion in a direction generally parallel to the lower surface of the base, and wherein, when the collection cartridge is coupled to the coupling portion—
the collection cartridge is fluidly connected to the portion of the outflow channel to receive the flow of the bodily fluid in the direction generally parallel to the lower surface of the base; and
the axis of the collection cartridge extends generally parallel to the lower surface of the base.
